Power banks consist of shells, interfaces, batteries, and circuit boards. The shell provides physical protection for internal components and prevents dust ingress. Given that power banks contain electrical elements like batteries and circuit boards, risks like battery short circuits and circuit board failures can potentially cause fires.
Flame-retardant PC/ABS alloy materials offer significant advantages for power bank shells:
Superior Flame Retardancy: These materials provide excellent flame retardant properties, achieving a VO flame retardancy rating (flame extinguishes immediately). They are environmentally friendly, halogen-free, and feature low smoke and low toxicity emissions. In the event of a battery fire, the shell slows the burning speed, reducing fire risk.
Excellent Mechanical Properties: The alloy boasts high impact strength and good toughness. This enables the shell to resist collision, extrusion, and falling during daily use without cracking or damage, protecting internal electrical components and extending the product's service life.
Good Temperature Resistance: Maintains dimensional stability across a wide temperature range, ensuring reliable charging and operation under various environmental conditions.
Processing Advantages: Offers good fluidity, making it easy to process and form. This facilitates injection molding of shells in various sizes and shapes, enhancing design flexibility and production efficiency.
Flame-retardant PC/ABS alloy is an ideal material choice for enhancing the safety, durability, and manufacturability of power bank shells.
